Answer:
13/20
Step-by-step explanation:
To add fractions without the common denominator, you have to make them equal so
1/4 x 5 = 5/20
2/5 x 4 = 8/20
5/20 + 8/20 = 13/20
Answer:
13/20 miles.
Step-by-step explanation:
[tex]\frac{1}{4} +\frac{2}{5}[/tex]
= [tex]\frac{5}{20} +\frac{8}{20}[/tex] (find the common denominator and convert the fractions)
= [tex]\frac{13}{20}[/tex]
13/20 is the most simplified it will go, so you will have walked 13/20 miles.

Each of the c children at a park will receive at least 3 balloons. If 150 balloons are given out in all, what is the maximum number of children that can go to the park before they run out of balloons?
Answer:
50 children can go to the park before they run out of balloons.
Step-by-step explanation:
If each child gets 3 balloons each, there will be 50 kids who can go in the park before they run out of balloons. 150 (balloons given out in total) / 3 (number of balloons each child receives) = 50 (number of children who can go into the park before balloons run out.)

The Chang family is on their way home from a cross-country road trip. During the trip, the function D (t) = 3260 - 55t can be used to model
their distance, in miles, from home after t hours of driving.
part a:find D(12) and interpret the meaning in the context of the problem. part b: if D(t) =2490, find the value of t and interpret its meaning in the context of the problem
Answer:
See below.
Step-by-step explanation:
D(t) = 3260 - 55t
The function that shows their distance from home as a function of time shows that they started 3260 miles from home and are driving at 55 miles per hour.
part a:
D(12) = 3260 55(12)
D(12) = 3260 - 660
D(12) = 2600
Interpretation: After 12 hours of driving home, they are 2600 miles from home.
part b:
D(t) = 2490
3260 - 55t = 2490
-55t = -770
t = 14
Interpretation: When they are 2490 miles from home, they have driven for 14 hours.

ANSWER FAST PLZZZZZ Give examples of a simple interest amortized loan with fixed monthly payments.
this is amortization or something
The fixed monthly payment for this loan is $186.07.
Each month, the borrower will make a payment of $186.07, which will include both interest and principal.
The interest portion of the payment will decrease over time, while the principal portion will increase until the loan is fully paid off at the end of the 5-year term.
What is simple interest?It is the interest calculated on the principal at a given rate for a time period.
We have,
Here is an example of a simple interest-amortized loan with fixed monthly payments:
Loan amount: $10,000
Interest rate: 5% per year (0.42% per month)
Loan term: 5 years (60 months)
To calculate the fixed monthly payment, we can use the formula:
P = (Pv x r) / (1 - (1 + r)^(-n))
where:
P = monthly payment
Pv = present value of the loan (the amount borrowed)
r = monthly interest rate
n = total number of payments
Substituting the given values,
P = (10,000 x 0.0042) / (1 - (1 + 0.0042)^(-60))
P = $186.07 (rounded to the nearest cent)
Therefore,
The fixed monthly payment for this loan is $186.07.
Each month, the borrower will make a payment of $186.07, which will include both interest and principal.
The interest portion of the payment will decrease over time, while the principal portion will increase until the loan is fully paid off at the end of the 5-year term.

If a and b are two distinct rational numbers, then which of the following statements is true?
a+b is always a rational number while a−b is not always a rational number.
Both a+b and a−b are not always rational numbers.
Both a+b and a−b are always rational numbers.
a+b is not always a rational number while a−b is always a rational number.
pls add explanation if possible
Answer:
Both are rational.
Step-by-step explanation:
As a rational number can be written in the form p/q where p,q are co-prime integers, let a=p1/q1 b=p2/q2.
And we know the product of two integers is an integer
p1q2, p2q1 are integers. And the sum or difference of two integers is rational, rather being specific, it is an integer.
Thus a+b and a-b is rational.

The area of the rectangular portion of the window can be represented by the function A(x) = 2x^2 + 10x. The area of the trapezoidal portion can be represented by the function A(t) = 6((x + 15) + (2x + 10)/2). Formulate a function A(w) that can be used to represent the area of the entire window.
A(w) = 9x + 75
A(w) = x(2x + 10)
A(w) = 21x^2 + 75x
A(w) = 2x^2 + 19x + 75
The function A(w) that can be used to represent the area of the entire window is 2x^2+17x+95.
We have given that,
The area of the rectangular portion of the window can be represented by the function A(x) = 2x^2 + 10x.
The area of the trapezoidal portion can be represented by the function A(t) = 6((x + 15) + (2x + 10)/2).
A(t)=6x+90+x+5
A(t)=7x+95
What is the area of the formula?[tex]Area\ of \ the\ rectangle=Length \times width[/tex]
Therefore the function A(w) that can be used to represent the area of the entire window is
A(W)=A(t)+A(x)
A(W)=7x+95+2x^2 + 10x
A(W)=2x^2+17x+95
The function A(w) that can be used to represent the area of the entire window is 2x^2+17x+95.

Data is collected on the number of ice cream cones sold in a shop on a certain day and the number of people wearing sunglasses visiting the shop that same day. What type of relationship is most likely to exist between these two variables?
1. positive correlation and causal relationship
2. negative correlation and causal relationship
3. positive correlation but not causal relationship
4. negative correlation but not causal relationship
Answer:
3. positive correlation but not causal relationship
Step-by-step explanation:
A positive correlation is when one factor increases, the other factor increases as well.
A negative correlation is when one factor increases, the other factor decreases.
A causal relationship is when one factor causes the other factor change in a certain way (i.e. increase or decrease).
More people buy ice cream as the day becomes hotter and sunnier. This also applies to people choosing to wear sunglasses. Therefore, there is a positive correlation between the two (because both increase). However, this is not a causal relationship because the cause of both is the hotter and sunnier day.

Answer:
The minimum unit cost is $9374.
Step-by-step explanation:
The unit cost C for making x engines is given by the quadratic function:
[tex]C(x)=0.3x^2-162x+31244[/tex]
We want to determine the minimum unit cost.
Since this is a quadratic function with a positive leading coefficient, the minimum value will be its vertex. The vertex of a quadratic can be found using the following formulas:
[tex]\displaystyle \text{Vertex}=\left(-\frac{b}{2a}, f\left(-\frac{b}{2a}\right)\right)[/tex]
In this case, a = 0.3, b = -162, and c = 31244.
Find the x-coordinate of the vertex:
[tex]\displaystyle x=-\frac{(-162)}{2(0.3)}=\frac{162}{0.6}=270[/tex]
In other words, in order to achieve the minimum cost, only 270 engines must be made.
Then to find the minimum cost, substitute the value back into the function. So:
[tex]C(270)=0.3(270)^2-162(270)+31244=\$ 9374[/tex]
The minimum unit cost is $9374.
Ryan deposited $6,700 into an account at the Town Bank, earning 3.4% interest compounded annually. He made no deposits or withdrawals. Write and solve the equation to find the amount of money in his account after 4 years. Round to the nearest cent.
Answer: The amount of money in his account after 4 years = $7,658.73
Step-by-step explanation:
If interest is compounded annually, then formula to compute amount :
[tex]A=P(1+r)^n[/tex], where P+ principal value, r= rate of interest, n= time ( in years).
As per given,
P= $6700 , r = 3.4% =0.034, n =4
[tex]A=6700(1+0.034)^4\\\\=6700(1.034)^4\\\\=6700(1.14309455234)\approx7658.73[/tex]
Hence, the amount of money in his account after 4 years = $7,658.73
